Here are pics of my 03 Cobra with MM coilovers, moderate lowering, & MM taper style bumpsteer kit. The angles of the control arms & tie rods of my Cobra don't look that much different than yours.
However, you cannot minimize bumpsteer by simply eye balling the control arm & tie rod angles & trying to match them up by adding bumpsteer shim stacks at tie rod ends.
You need to measure the amount of bumpsteer with a bumpsteer gauge at various points thru the range of your suspension movement to know how much bumpsteer you have & adjust it out with shims.
Offset rack bushings with a stock k-member quite possibly would increase bumpsteer. Offset rack bushings usually are appropriate to use with aftermarket k-members where the control arm attachment is raised above the stock location.
